        <h2>Description</h2>
        <p> 
      These statements are global value <a class="link" href="assign.html" title="="><em class="citetitle">assignments</em></a>, made
      at the beginning of an orchestra, before any instrument block is
      defined. Their function is to set certain <a class="link" href="OrchKvar.html#VariableTypes" title="Table 3. Types of Variables"><em class="citetitle">reserved symbol
      variables</em></a> that are required for
      performance. Once set, these reserved symbols can be used in
      expressions anywhere in the orchestra. 
    </p>
      </div>

        <h2>Syntax</h2>
        <pre class="synopsis"><span class="command"><strong>kr</strong></span> = iarg</pre>
      </div>
      <div class="refsect1">
        <a id="idp118399568"></a>
        <h2>Initialization</h2>
        <p>
      <span class="emphasis"><em>kr</em></span> = (optional) -- set control rate to <span class="emphasis"><em>iarg</em></span> samples per second. The default value is 4410.
    </p>
        <p>
      In addition, any <a class="link" href="OrchKvar.html#GlobalVariables"><em class="citetitle">global variable</em></a> can be initialized by an <span class="emphasis"><em>init-time assignment</em></span> anywhere before the first <a class="link" href="instr.html" title="instr"><em class="citetitle">instr statement</em></a>.  All of the above assignments are run as instrument 0 (i-pass only) at the start of real performance.
    </p>
        <p>
      Beginning with Csound version 3.46, <span class="emphasis"><em>kr</em></span> can be omitted. Csound will use the default values, or calculate <span class="emphasis"><em>kr</em></span> from defined <a class="link" href="ksmps.html" title="ksmps"><em class="citetitle">ksmps</em></a> and <a class="link" href="sr.html" title="sr"><em class="citetitle">sr</em></a>. It is usually better to just specify <a class="link" href="ksmps.html" title="ksmps"><em class="citetitle">ksmps</em></a> and <a class="link" href="sr.html" title="sr"><em class="citetitle">sr</em></a> and let csound calculate <span class="emphasis"><em>kr</em></span>.
